Rosie Huntington-Whiteley dared to bare her bra on Wednesday night as she attended a dinner to celebrate her new M&S range at the Dover St Arts Club.
She was looking seriously sexy in her frilly sheer black Dolce & Gabbana number, which she somehow managed to keep chic, despite the fact her lacy black bra was on full show.
She paired the look with a stylish chignon, cigarette pants and glitzy stilettos.
Throughout the night, she tweeted a pic from inside the venue, writing: "Beautiful table display at my dinner for all the best London fashion editors to celebrate my #rosieforautograph collection."
Earlier in the day, Rosie struck a pose as she attended a photo call to launch the new Rosie for Autograph Sleepwear Collection at M&S Marble Arch.
She tweeted: "Officially launching my sleepwear collection today @marksandspencer "#RosieForAutograph #ProudMoment."
She looked chic and stylish in a black skinny knit top and £299 animal-printed leather skirt, both, shockingly, from Marks & Spencer.
The new sleepwear range features everything from satin pyjamas for £35 to a £149 cashmere jumper and snood.
Rosie even showed everyone how to wear the cashmere top, writing on Instagram: "Cosy cashmere sweater from my line @marksandspencer #rosiesleepwear #roselingerie #rosieforautograph On sale NOW!!
